Among the latest to announce Lion compatibility is Piriform, the privately owned UK software developer dedicated to creating top quality applications for Windows and Mac. The developer announced that CCleaner for Mac Beta 3 has been rolled out to the masses and that this release fixes compatibility issues with Lion. The developer also said that this third Beta release adds Chrome and Firefox 6.0 support.

If you would like to get CCleaner for Mac Beta 3, you can get it straight from Piriform here. Do not get the application unless you understand the risks of using Beta products. They can be buggy, they may not work properly, they may ruin your day. Beta releases are meant for advanced users only.
